Abstract: |
The application of acoustic method to measure suspended particle size and concentration profile has been gaining backscattered signal require an inversion algorithm with known acoustic backscatter system constant. This need a system calibration. Using glass spheres which has regular shape as suspension sediments the calibration can be conducted with known scattering characteristics. The result shows that a triple frequency acoustic backscatter system can be calibrated in such way. |
